Specication describing a new and useful Improvement in Wagon-Springs,invented by ALEXANDER W. MCKOWN, of Honesdale, in the county of Wayneand vState of Pennsylvania.

My invention consists of thejcombination of auxiliary springs with theordinary springs of a Wagon and connecting devices, whereby the saidauxiliary springs may be utilized to reinforce the ordinaryspringsaceording te the Weight ofthe load, and thus avoid the pres- 4entobjectionable practice of using the same of connecting the said springs.Fig. 5 is a 1ongitudinal section of metal carriage-springs, ar-

ranged according to my improvement, and Fig. 6 is a cross-section ofFig. 5.

Similar letters of reference indicate corresponding parts.

A represents the ordinary springs, and Bthe auxiliaries. with across-bar, C o1' D, or both, rigidly connected to them at the ends.These bars carry cranked, pivoted, or hooked devices E, F,

G, H, I, or K, or any equivalent thereof, ar-

ranged to conne the auxiliary springs to the cross-bars to re-enforcethe main springs or to disconnect them, as may be required by tieconditions of the load.

Having thus described my invention, I claim Ias new and desire to secureby Letters Patent- The combination, with the main springs A, of theauxiliary springs B, cross-bars C or D, and connecting devices fortemporarily connecting said auxiliary springs to the cross-bars tore-enforce the main springs, all substantially as specified.
